Aim: The aim of this study is to evaluate the relationship between the gummy smile and: Length of the upper lip; height of the clinical crown and inter-labial gap and to help clinicians to indentify the most significant clinical parameters that associated with gummy smile. Materials and methods: The Sample comprised of 35 females, aged 20-35 years, matched to 35 controls for age sex and race, selected randomly from outpatient clinic at Khartoum dental teaching hospital and from Khartoum University, Faculty of Dentistry. A Sony 10 mega pixel Digital Camera was used for photography and Photoshop software program for the measurements. Results: Among the three parameters, the height of the clinical crown of maxillary anteriors teeth showed significant result of a p-value 0.04 and the Inter-labial gap showed highly significant result p-value 0.000 when comparing the sample to the controls. The inter-labial gap showed a high correlation to the gummy smile level p-value 0.016. Conclusion: A proper diagnosis and treatment planning of gummy smile should be aimed to correct these parameters and especially the inter-labia gap to normal value at the end of the treatment either by orthodontic or orthognathic surgery.
